Definition - What does Biodiesel mean?
Biodiesel is a petroleum "diesel fuel" product produced from vegetable oils, animal fats or recycled restaurant grease. Since it is prepared without wasting any non-renewable resources it is a renewable and biodegradable fuel. It performs similar to other diesel fuels; however, biodiesel burns completely and causes less pollution. Therefore, it is considered to be cleaner than diesel fuel.
Corrosionpedia explains Biodiesel
Biodiesel is a liquid fuel often referred to as B100 or neat biodiesel in its pure, unblended form. Like petroleum diesel, biodiesel is used to fuel compression-ignition engines.
Some characteristics of biodiesel:
|Kinematic viscosity at 40°C (104°F)||4.0 to 6.0|
|Cetane number||48 to 65|
|Higher heating value, Btu/gal||Approx 127,960|
|Lower heating value, Btu/gal||Approx 119,550|
|Density, lb/gal at 15.5°C (59.9°F)||7.3|
|Oxygen, by dif. wt%||11|
|Boiling point, °C||315-350|
|Flash point, °C||100-170|
|Sulfur, wt%||0.0 to 0.0015|
|Cloud point, °C||-3 to 15|
|Pour point, °C||-5 to 10|
